Consumer behavior and access to desired services is the real issue. A broadcast standard that few people are using, a standard that leaves vast swaths of spectrum (white spaces) unused to protect the channels that are used is not efficient by any measure. The fact that it is virtually useless for mobile screens is completely OUT OF SYNC with modern realities. Consumers are using mobile devices and cellular data to watch video today. This trend is increasing as more popular content becomes available to mobile devices, via authentication that the mobile user also PAYS for this content. ESPN is especially relevant here. It is highly likely that the mobile audience will be larger - and more valuable from a financial perspective - than the audience broadcasters can attract in the 600 MHz spectrum. This assumes that the existing broadcast audience will continue to be served via the large swath of spectrum that broadcasters will continue to use - hopefully more efficiently by combining existing channels in multicast multiplexes. And most important, there is good reason to believe that using the 600 MHz spectrum for LTE Broadcast WILL free up bandwidth that is currently being used for unicast video streams. Making popular content available in multicasts frees up bits that are currently being used inefficiently for replicated unicast. It is well worth noting that broadcasters COULD have owned this market, but chose an inappropriate transmission standard, and appear ready to repeat this mistake with ATSC 2.
